How do I center blocks of text on my form?

I'm trying to center blocks of text (fields) on my form underneath my category headings, but I'm not having much success. Can you please help me with this issue? 

I think you have figured this out already. I see some texts in the form are now centred. Please let us know if you require additional assistance.

Actually I'm still struggling to center the text blocks. I was able to center headers on my form, but need code/help centering the different fields within the headers. Can you help me with this? Thanks in advance!!

I want to center all fields from "Parish or Mission" to "Please leave a comment..." on the first page. 

Add this CSS code to your form:

.form-section {

    margin :0 auto !important;

}

.form-line {

    text-align : center !important;

}

.form-label.form-label-top {

    text-align : center !important;

}

.form-input-wide.jf-required {

    margin :0 auto !important;

}

Thanks for this help, but the code didn't align dropdown inputs. Is there a way to correct this? 

I am not exactly sure if I understood you correctly. Dropdown fields should be center aligned. If you also want to center align dropdown options that was selected the add this CSS code as well. 

select {

    text-align-last : center;

    text-align : center;

    -ms-text-align-last : center;

    -moz-text-align-last : center;

}

Fields that are not aligned properly are Shrink fields.
